The Gnome-Mobile is a 1967 Disney film, directed by Robert Stevenson. It was one of the last films personally produced by Walt Disney. It was based on a 1936 book by Upton Sinclair titled The Gnomobile. Walter Brennan gives a double performance as D.J. Mulrooney, the kind-hearted lumber tycoon of Irish descent; and as the irascible 943 year-old gnome Knobby. The children, Elizabeth and Rodney, were played by Karen Dotrice and Matthew Garber, familiar from their roles as Jane and Michael Banks in Mary Poppins. Tom Lowell who plays the young gnome Jasper in this movie, also appeared in the 1965 Disney film That Darn Cat! as Canoe, the befuddled surfer boyfriend of Hayley Mills. The Gnome-Mobile was both Matthew Garber and Ed Wynn's last movie role. Wynn died of throat cancer before the movie was released and Garber died ten years later, having contracted hepatitis while visiting India. Richard and Robert Sherman contributed the song "Gnome Mobile." Show Less
